Capturing
existing 3-D data is often one of the first
steps in a design project. Rhino has always
directly supported both 3-D digitizing hardware
and 3-D scanned point cloud data. Rhino 5 has enhanced support for:

Large point clouds. 3-D
scanners have become faster and cheaper,
making huge scan files more common.
Rhino's 64-bit
support and enhanced support for
graphic co-processors has made it possible to work with
these
large point clouds.
